The transepithelial transport of ascorbate across the isolated rabbit ciliary epithelium (CE) was investigated. Unidirectional 14C-ascorbate fluxes were measured in the presence of equal concentrations of ascorbate on both sides of the tissue within the range of 0.025 to 1 mM. The blood to aqueous (Bl----Aq) flux increased from 6 to 95 nmoles/hr and showed nonlinearity and saturation. The aqueo...

In photosystem I (PS I), phylloquinone (PhQ) acts as a low potential electron acceptor during light-induced electron transfer (ET). The origin of the very low midpoint potential of the quinone is investigated by introducing anthraquinone (AQ) into PS I in the presence and absence of the iron-sulfur clusters. Solvent extraction and reincubation is used to obtain PS I particles containing AQ and ...

We have reviewed published anthraquinone applications for international pest management and agricultural crop protection from 1943 to 2016. Anthraquinone (AQ) is commonly found in dyes, pigments and many plants and organisms. Avian repellent research with AQ began in the 1940s. In the context of pest management, AQ is currently used as a chemical repellent, perch deterrent, insecticide and feed...

In this study, the in vitro effects of amodiaquine (AQ) monotherapy on the egg output of paired adult Schistosoma mansoni worms and their survival during in vitro culture were assessed. In addition, the gross morphological alterations of male and female worms caused by AQ were visually observed under a dissecting microscope. AQ significantly reduced the daily egg output of paired adult S. manso...

Our objective was to examine the overlap between autistic traits and other behavioral problems in a general population sample, and explore the extent to which this overlap is due to genetic or environmental factors. Youth Self Report (YSR) data were collected in a general population sample of 424 twin pairs at 18 years of age, and their nontwin siblings. In 197 of these twin families, self-repo...

Objective: To examine the overlap between autistic traits and other behavioural problems in a general population sample, and explore whether this overlap is of genetic or environmental origin. Method: Youth Self Report (YSR) data were collected in a general population sample of 424 twin pairs at 8 years of age, and their non-twin siblings. In 97 of these families self-report ratings on the Au...

Predictors of recurrence in lone atrial fibrillation have not been clearly identified. Acoustic quantification (AQ) is a promising method in the assessment of left atrial (LA) volumes. The purpose of the present study was to investigate the potential of LA volumes obtained by standard manual tracing and AQ methods in predicting AF-recurrence after restoring the sinus rhythm in patients with lon...

We investigated the safety and efficacy of amodiaquine alone (AQ) and combined with artesunate (AQ + AS) in 308 Rwandan children 6-59 months old with uncomplicated Plasmodium falciparum malaria attending three sentinel sites. The two treatment regimes were well tolerated and no serious adverse events were recorded. After excluding new infections, children treated with AQ + AS had fewer clinical...

OBJECTIVES To determine the efficacy of a novel antimicrobial compound, AQ+, against a genetically heterogeneous collection comprising 213 Staphylococcus aureus isolates from global sources. AQ+ is an aqueous preparation containing 0.5% 8-hydroxyquinoline. METHODS MICs were found for all the isolates tested using the BSAC microdilution method. Time-kill studies were performed according to NCC...
